SEECIFIGATION forming part of Letters Patent No. 683,220, dated September 24, v1901.

Application filed February 23, 1901. Serial No. 48,522. (No model.)

T IZZ whom t may concern:

Be it known that We, SAMUEL F. NEILL and JULIEN E. TINKER, citizensof the United States, residing at Bradford, in the county of McKean and State of Pennsylvania, have invented certain new and useful Improvements in VVheelS; and we do hereby declare the following to bea full, clear, and exact description of the invention, such as will enable Oth- Io ers skilled in the art towhich it appertaius to make and use the same. i

Qur invention is an improvement in wheels for vehicles; and it consists in the novel features of construction and combination of parts hereinafter fully described, reference being Vhad to the accompanying drawings, which illustrate one form in which we have contemplated embodying our invention and several slight modifications thereof.

Our invention is fully disclosed in the following description and claims.

Referring to the said drawings, Figure l represents a sectional view of a wheel embodying our invention. Fig. 2 represents a partial sectional View of a slight modification. Fig. 3 isa view similar to Fig. 2, showing another modification. Fig. 4 is a view showing cross-sections of auxiliary treads of different shapes embodying our invention. 3o Fig. 5 is a sectional View of another modification.

The object of our invention is to provide a wheel with a lateral flange or lateral flanges forming an auxiliary tread of slightly-less diameter than the main tread of the wheel.

In the drawings, A represents the hub of a wheel, B the rim orfelly, and Othe spokes. The wheel is shown as constructed of wood in the ordinary manner; but the wheel may 4o be composed entirely of metal or partly of wood and partly of metal, if preferred. The wheel may be provided with either a metal tire or a rubber or other form of cushion or yielding tire, as referred. In this instance we have shown the Wheel provided with a metal tire D, (see Fig. 1,) which is grooved to retain a rubber tire E, held therein by a wire or other suitable core F, the tread of the wheel being the outer periphery of the 5o rubber tire. (Indicated at e.) c.

G G represent annular flanges or rings, each of which is provided at one side with an inwardly-extending attaching-flange g, which is bolted or otherwise secured to the rim or felly of the Wheel. The wheel may be supplied with one of these lateral flangesV G; but we prefer to provide one on each Side, the bolts g extending through lthe felly and through the attaching flanges g g. The flanges G G are of less diameter than the tread of the wheel, so that when the wheel is running over a hard road-bed it will run on the normal tread e; but when it runs over sandy, muddy,or other yielding road-beds it will run upon the auxiliary tread formed by the flanges G G, as the main tire E will sink into the yielding bed. The auxiliary tread prevents the wheel from sinking farther than the difference in the radii of the main and auxiliary treads, and the auxiliary tread affords a broad surface to bear up the wheel and its load and also gives increased traction, which is very desirable in the case of self-propelled vehicles.

In some instances we prefer to provide the outer edges of the auxiliary tread with inwardly-extending rims or flanges, as shown in Fig. 2, in which G' G represent the lateral flanges and g2 g2 the outer rims or flanges thereof, which Serve to largely prevent sand, mud, or water from Working over the auxiliary tread, which would cause the wheel to draw hard. In Fig. 4 we have shown crosssections of several styles of auxiliary treads provided with inwardly curved or bent flanges ga ga for this purpose.

InFig. 3 we have shown a modified construction, in which the lateral flanges G2 G2 are provided with the inwardly-extending attaching-fiangcs g4 g4 and also with outwardly-extending flanges g5 g5, which form the lateral retaining-walls or the cushiontire E2. This construction is particularly advantageous for applying our invention to any ordinary wheel, so as to provide it with a cushioned main tread and the broad auxiliary tread.

In Fig. 5 We have shown our invention applied to an ordinary Wheel having a metal tire. In this figure B3 is the felly, l)3 the tire,

IOO

and G3 G3 the lateral iianges, provided with the securingfanges gf' gc.

`What We claim, and desire to secure by Letters Patent, is- -v l. The combination with awheel, of an annular auxiliaryiread of less diameter than the tread of the Wheel, provided with an attaching-ange and means for securing said attaching-flange to the Wheel, substantially as described.

2. The combination with a Wheel, of an annular auxiliary tread on each side of the Wheel of less diameter than the Jfread of the Wheel each provided with an inwardly-extending attaching-flange adapted to be secured to the Wheel, and an outwardly-extending ange, said outwardly extending flanges forming lateral retaining-Walls for the Wheel-tire, substantially as described.

3. The combination with a Wheel, of an annular auxiliary tread on each side of the Wheel, of less diameter than the tread of the Wheel, eacliprovided with means for attaching it to the Wheel, and With an inwardlyextending ange at its outer edge toprevent sand and mud from running over saidauxiliary tread, substantially as described.

In testimony whereof We afix our signatures in the presence of two witnesses.
